PFAS in Pizza Stones and Pizza Steels, 141 Graded

We graded 141 pizza stones, pizza steels and pizza pans. The big picture is reassuring. 118 of them grade 65 or better out of 100, most because a ceramic or cordierite stone, a carbon steel plate or a cast iron pan does its job without a non-stick coating. The low grades belong to pizza pans and grilling packs with a non-stick coating of unstated type, at 15.

How we graded these

Every grade here is a model-based estimate built from publicly available product information and manufacturer disclosures, not a lab test performed by our team. A high score means lower concern based on reviewed sources, never PFAS-free and never safe. Across the 130 products the spread is two at 90, eight at 75, five at 70, 104 at 65, one at 40, one at 35, one at 30 and eight at 15. Look up any product in our PFAS product finder.

Stones, steels and coated pans

A pizza stone is fired ceramic or cordierite, a mineral that handles sudden heat. A pizza steel is a plate of carbon steel. Neither needs a coating, and 103 products grade 65 on the same three factors, the cookware baseline, a credit for a material not associated with PFAS, and a penalty because the maker says nothing about PFAS. Eight carbon steel plates and cast iron pans grade 75, because our model gives bare metal a larger credit. Two Our Place ceramic stones grade 90. They carry the same material credit as the stones at 65, but our records credit them with Our Place's PFAS statement instead of the penalty for saying nothing. That statement is about Our Place's ceramic non-stick coating, and we have not verified it. Five stones that had been listed under GreenPan, including two Big Green Egg stones, moved from 90 to 65 on 17 September 2026, because GreenPan does not sell them and its statement does not cover them.

Coated pizza pans are a different product. Eight grade 15 because they carry a non-stick coating whose type is not stated and no PFAS statement from the maker. Five ceramic non-stick pans and stones from Caraway and GreenPan grade 70. Caraway says its ceramic coating is made without PTFE, PFOA and PFAS, and GreenPan says its Thermolon coated food contact surface is free of PFAS, including PTFE and PFOA. The 70 is the cookware baseline of 30, plus 10 for a named coating, minus 10 for the statement. Neither brand is MADE SAFE certified. An earlier version of this guide said these pans carried MADE SAFE certification and graded some of them 90 or 100. That was wrong, and we corrected it on 17 September 2026. Our Place's Wonder Oven Baker's Kit grades 40, with Our Place's statement but a non-stick coating its record does not name. A glazed stone is not a non-stick coating, and the glazed stones here grade like the unglazed ones.

A correction to this guide

An earlier version of this guide put the IKEA Nordic Ware stone set at the top at 90, said the stones at 65 were held back by incomplete disclosure about glazes and raw materials, and listed a Farberware stone and a Sur La Table no-slip stone among the worst. None of that was supported by our records. The 90 was a record that had skipped the silence penalty, several ceramic stones had been credited as if they were bare metal while several bare steel plates had not, and the two stones at 15 had a non-stick coating their listings never describe. We corrected all of it on 16 September 2026.

What to avoid

• Pizza pans and crispers sold as non-stick with no coating type named and no PFAS statement. That is where the eight grades of 15 sit.
• Paying more for a stone on PFAS grounds. Almost every stone grades the same 65.
• Reading 65 as a warning. It reflects a maker saying nothing about PFAS on a product with no coating.

Our pick

Based on available materials and data, for crisp crusts we would choose the Baking Steel The Original at 75 out of 100, bare carbon steel with no coating. If you prefer a stone, any cordierite or ceramic stone here is a sound choice, such as the Emile Henry Pizza Stone at 65. If you want a non-stick pan, the Caraway Ceramic Nonstick Pizza Pan grades 70, on Caraway's statement that its ceramic coating is made without PTFE, PFOA and PFAS, which we have not verified. These grades are estimates built from disclosed materials, not laboratory proof, and nothing here is being called PFAS-free or safe by us.

FAQ

Do pizza stones contain PFAS?

Ceramic and cordierite are not fluorinated materials, and none of the 103 products at 65 has a coating on record. Their makers publish no PFAS statement, so we record lower concern based on materials rather than a confirmed absence.

Is a pizza steel better than a pizza stone for PFAS?

Both are uncoated. Bare carbon steel plates grade 75 and ceramic stones 65 in our data, a difference in how our model credits bare metal rather than a finding against stone.

Are glazed pizza stones a PFAS concern?

A ceramic glaze is fused glass, not a fluorinated non-stick coating. The glazed stones we graded grade 65, the same as unglazed ones.

Which pizza pans should I avoid?

Non-stick pizza pans, crispers and grilling packs whose coating type is not stated and whose maker says nothing about PFAS. Eight products grade 15 for that reason, including the Farberware Pizza Crisper and the Cuisinart Pizza Grilling Pack.
